PROBLEM TO BE SOLVED: To make one sensor unit two-or three-dimensional magnetometric sensor with making its size small. SOLUTION: The magnetometric sensor 1 comprises an excitation core 2 having an excitation coil 3 wound and multiple detection cores 4 having a detection coil 5 wound. At least one detection core 4 is placed in a moving direction of the excitation core 2 and an object to be detected 6 relatively moving and in a direction crossing to the moving direction.
